import javafx.beans.property.SimpleIntegerProperty;

public class Test {
public static void main(String[] args) {

IntegerProperty d1 = new SimpleIntegerProperty(1);

IntegerProperty d2 = new SimpleIntegerProperty(2);

d1.bindBidirectional(d2);

System.out.print("d1 is " + d1.getValue()

+ " and d2 is " + d2.getValue());

d1.setValue(3);

System.out.println(", d1 is " + d1.getValue()

+ " and d2 is " + d2.getValue());

}

◦ d1 is 1 and d2 is 2, d1 is 3 and d2 is 3
◦ d1 is 2 and d2 is 2, d1 is 2 and d2 is 3
◦ d1 is 1 and d2 is 2, d1 is 1 and d2 is 3
